Is anyone familiar with the yz-24a incubator? My hydrometer seems to be stuck on 69... insert jokes.... even when I add double what is needed. Even added a sponge full of water. It's been running for half a day and is going to be my hatching out incubator since it is missing a piece to turn my eggs. My usual hydrometer I used to use is missing of course. Will have to buy one tomorrow. Can anyone tell me if this means its completely broke, or did I do something wrong? My eggs dont go in til tomorrow night.
